My 2 month old daughter has a hamengioma above her upper lip. some doctors say its a capillary hamengioma while others say its cavarnous. what is the difference and how can we ascertain which one is it?

Small/large vessels: Infantile hemangiomas are benign vascular lesions that have a characteristic clinical course marked by early proliferation and followed by spontaneous involution by 9 years old. A capillary hemangioma is the most common type. It is made up of small capillaries that are normal in size and diameter, but high in number. A cavernous hemangioma is made up of larger blood vessels that are dilated.
